both those autoglym products are polshs, not wax. i think the bottle said to put the extra gloss ontop, i think i did this when i got my car.
WAX is a top dressing.
not tried dodo, i tried vicotias concours the other day on a few panels and didnt see any different at all. not sure if it was a bit dodgy as i got a sample from someone... seemed runny but everyone says its not really...
